Problems solved by technology

The centralized power supply system has the advantages of easy manual management, etc., but there is also the danger that the power source is concentrated in one place, and once the power source fails, it will cause the danger of power supply failure for the whole ship, and ship generators generally have the disadvantages of large pollution, etc., and are being used battery replacement
However, the capacity and power of batteries are not as good as those of generators, and it is difficult to meet the requirements of high-power and high-capacity applications. Even if they are barely met, the service life of batteries may be reduced, or frequent failures may occur due to long-term exceeding the normal application range of batteries, which limits the use of batteries in ships.

[0045] refer to figure 1 , the distributed marine power supply system described in this embodiment includes a plurality of power distribution cabinets 100 and several storage battery units 200;

[0046] Each of the power distribution cabinets 100 is respectively provided with a bus bar 300, and each of the said power distribution cabinets 100 is respectively provided with a first bus bar interface 301 and a second bus bar interface 302, so that the two bus bars 300 in each of the said power distribution cabinets 100 terminals are led out of the power distribution cabinet 100 through the first bus interface 301 and the second bus interface 302 respectively;

[0047] Each of the power distribution cabinets 100 is respectively provided with several power supply interfaces 303, and each of the power supply interfaces 303 is connected to the bus bar 300 in the power distribution cabinet 100 by lead wires;

[0048] At least one of the power distribution cabinets 100 is provided wit...

Embodiment 2

[0071] For the power management unit used in the distributed power supply system for ships described in Embodiment 1, a control method is designed for it in this embodiment, which includes the following steps:

[0072] S1. Detecting the current of the bus bar provided in each of the power distribution cabinets, thereby calculating the load of each of the power distribution cabinets;

[0073] S2. Detecting the energy storage state of each of the storage battery units connected to the battery interface; the energy storage state includes remaining power;

[0074] S3. Read the preset safe working time;

[0075] S4. According to the safe working time and the sum of the loads of all the power distribution cabinets, calculate the safe electric quantity;

[0076] S5. When the sum of the detected remaining electric quantities is less than the safe electric quantity, connect part or all of the storage battery units not connected to the battery interface with the corresponding battery i...

Embodiment 3

[0087] In each of the power distribution cabinets that meet the requirement of "forming a series connection," the first bus interface of the first power distribution cabinet is connected to the second bus interface of the last power distribution cabinet, so that each of the power distribution cabinets Under the condition that the internal busbars form a ring connection, and the battery interfaces are equally spaced and uniformly distributed on the ring-connected busbars", the control method of the power management unit may include the following steps:

Abstract

The invention discloses a distributed power supply system for ships, a control method and a storage medium. The system includes a power distribution cabinet, a storage battery unit and a power management unit. Each power distribution cabinet is respectively equipped with a bus bar, a power supply interface, a battery interface, The receiving interface, the first busbar interface and the second busbar interface, each power supply interface is connected to the busbar in the power distribution cabinet by lead wires, and each battery interface is connected to the busbar in the power distribution cabinet by lead wires. The interfaces are respectively connected to the storage battery units, and each power receiving interface is connected to the bus bar in the power distribution cabinet through lead wires. Each power receiving interface is used for and accepts external power supply respectively. The busbars in each of the power distribution cabinets are connected in series through the first busbar interface and the second busbar interface respectively. The power supply system of the present invention has high power supply stability and use flexibility. The invention is widely used in the technical field of ship power supply.

Description

technical field [0001] The invention relates to the technical field of ship power supply, in particular to a distributed ship power supply system, a control method and a storage medium. Background technique [0002] At present, the power supply on ships is realized by a centralized power supply system. In the centralized power supply system, the ship generator is the main power source, and the switchboard is used as the load distribution center equipment. The centralized power supply system has the advantages of easy manual management, etc., but there is also the danger that the power source is concentrated in one place, and once the power source fails, it will cause the danger of power supply failure for the whole ship, and ship generators generally have the disadvantages of large pollution, etc., and are being used Battery replaced. However, the capacity and power of batteries are not as good as those of generators, and it is difficult to meet the requirements of high-pow...
